Rolls Batteries

Batteries are the essential cornerstone of an off-grid or back-up system. The vast majority of batteries used in this sector use lead-acid technology but there is a growing interest in Lithium Ion batteries. Here we only focus on lead-acid as it is still far and away the most cost effective and user friendly method to store energy.

Batteries are an expensive part of a system and their cost arises from one simple aspect - they use a lot of the commodity lead.  The cost of batteries used to act as the energy store in an off-grid or back--up system will probably be a large proportion of the total system budget. As the bulk of this cost is unavoidable - the lead - it makes sense not to waste the money being invested, by buying the wrong type of battery or buying poor quality batteries.

In very simplistic terms, batteries (when connected in an electrical circuit) produce electrical current as the sulphuric acid reacts with the lead plates to form lead sulphate and, ultimately, water. When we recharge the battery we apply an electric current to reverse the process and reconvert it back to sulphuric acid and lead. When you hear people say that a battery should not be discharged fully - it is because allowing the lead and sulphuric acid to fully convert to lead sulphate and water makes it very difficult to reverse the reaction as water does not conduct electricity very well. So we try to ensure the 'electrolyte' (acid) remains at least a little bit acidic! This process will occur every time we discharge and recharge a battery, so we want this process to be as successful as possible (charge efficiency) and we want the battery to be able to do this as many times as possible (cyclic life). How well a battery does this is, in no small way, down to the design and manufacture of the battery. So, buying the right type of battery is important, but so is getting a good quality battery from a reputable battery manufacturer; it will save you lots of money in the long term.
